论文摘要
背景：Deuteron靶标中中子和质子的日食效应对于正确描述高能量Deuteron散射至关重要。细胞核散射不仅需要核核子的信息，而且还需要核与中子之间的相互作用，对于不稳定的核，不可直接测量核 - 中环横截面。 目的：我们通过Deuteron目标系统地评估了总反应横切，以探索从可测量的横截面中提取细胞核间隔相互作用的可行性。 方法：高能量核 - 核酸胶碰撞由Glauber模型描述，其中明确考虑了Deuteron的质子和中子构型。 结果：我们的计算再现了可用的实验性总反应截面数据，有关核核酸核的散射。探索了从核 - deuteron和核 - 普罗氏核总反应横截面中提取核 - 内核总反应截面的可能性。质子，中子和杜特隆靶标的核的总反应横截面可以很好地表达，从核物质半径和中子皮肤厚度方面，可以很好地表达。检查了总反应横截面的入射 - 能量依赖性。 结论：Deuteron目标的总反应横截面包括有关核 - 中子和原子核概要函数函数的信息。通过Deuteron和Proton目标测量横截面是提取核大小特性的有前途的工具。
Background: Eclipse effect of the neutron and proton in a deuteron target is essential to correctly describe high-energy deuteron scattering. The nucleus-deuteron scattering needs information not only on the nucleus-proton but also the nucleus-neutron interaction, for which no direct measurement of the nucleus-neutron cross sections is available for unstable nuclei. Purpose: We systematically evaluated the total reaction cross sections by a deuteron target to explore the feasibility of extracting the nucleus-neutron interaction from measurable cross sections. Methods: High-energy nucleus-deuteron collision is described by the Glauber model, in which the proton and neutron configuration of the deuteron is explicitly taken into account. Results: Our calculation reproduces available experimental total reaction cross section data on the nucleus-deuteron scattering. The possibility of extracting the nucleus-neutron total reaction cross section from nucleus-deuteron and nucleus-proton total reaction cross sections is explored. The total reaction cross sections of a nucleus by proton, neutron, and deuteron targets can be expressed, to good accuracy, in terms of the nuclear matter radius and neutron skin thickness. Incident-energy dependence of the total reaction cross sections is examined. Conclusions: The total reaction cross section on a deuteron target includes information on both the nucleus-neutron and nucleus-proton profile functions. Measuring the cross sections by deuteron and proton targets is a promising tool to extract the nuclear size properties.
